First conversion was to EI. Got a syncrospark and walboro carb adaptor from CH. Didn't like the 1/4" Plug so I tapped the head for 10mm. After a few flights the plug blew out of the head and had to make a brass insert in the head for the plug. Later tapped out the insert to 14mm and tried it on gas/glow. Performance was about the same as on gas. Fuel mix was 10% klotz technoplate and rest 87 oct gasoline.
